Fin radiatorDo you all know about this? From the literal meaning, it is clear what it is used for. Currently, there are many types of fin radiators on the market, and everyone should clarify their needs before making a purchase. Today, we will introduce some related information about fin radiators. Interested friends can take a look.
Nowadays, many new types of equipment have emerged in the industrial field, and these devices play a significant role during use, such as fin radiators, which are essentially heating panels, abbreviated as radiators. In the field of electronic engineering design, they are classified as 'passive heat dissipation components'. This explanation should make it clear. When in use, they mainly attach metals with good thermal conductivity, lightweight, and easy to process to the heating surface to dissipate heat through a composite heat exchange mode. The material of the fin radiator is gray cast iron. It is divided into column type, wing type, column-wing type, and plate-wing type based on structural form. In the future, everyone should distinguish them when buying. Moreover, it includes a main body and two connecting parts. Each end of the main body has two fixed holes, and there is a perforation in the middle part that extends outward to form a joining part on one side of the heat dissipation fin.
After understanding the basic information about fin radiators, let's take a look at other knowledge points. Currently, fin radiators primarily connect with heat pipes through perforations and connecting parts during use. At this point, it is important to know that the connecting parts extend vertically outward from both ends of the main body and include a vertical part and a bearing part. It is also essential to understand that the vertical part includes a container block and two receiving blocks. Each side of the receiving block forms a receiving part. Additionally, the fin radiator is parallel to the main body and has two fixed protrusions corresponding to the fixed holes on the main body. It has a long service life and can last as long as the building itself. The price of cast iron radiators in our country is low and has strong market competitiveness. Therefore, its role is quite significant.

How much do you know about finned heat sinks?
The characteristics of finned heat sinks are that the fins break through the original proportional limitations, resulting in good heat dissipation effects, and different materials can be used to make the fins. The drawbacks are also quite obvious, as the heat sink and the base are bonded with thermal paste and solder, which can cause interface resistance issues that affect heat dissipation. To improve these shortcomings, two new technologies have been applied in the field of heat sinks.
Introduction to the characteristics of finned heat sinks.
The finned heat sink is a device used for electronic components that are prone to heating in electrical appliances. It is made of aluminum alloy, yellow or bronze, and comes in plate, sheet, or multi-sheet shapes. For example, the CPU in a computer requires a considerable size, and the power tubes, line tubes, and amplifier tubes in televisions all need to dissipate heat. Typically, a layer of thermal grease should be applied to the contact surface of the electronic components to more effectively conduct the heat generated by the components, which is then dissipated into the surrounding air.
Introduction to the advantages of finned heat sinks
The finned heat sink primarily achieves heat dissipation through conduction, involving dielectric heat sinks that are in direct contact with the processor. After absorbing heat, it dissipates through convection. During the convection process, the area is mainly determined by the surface area of the fins. Common methods used in the industry include: increasing the number of fins and increasing the length of the fins. One of the reflected data points is the 'thickness ratio', which is the ratio of fin thickness to its height.
Introduction to finned heat sinks
The finned heat sink primarily achieves heat dissipation through conduction, involving a medium heat sink that is in direct contact with the processor. After absorbing heat, the heat sink dissipates it through convection. In the convection heat dissipation process, the heat dissipation area is mainly determined by the surface area of the heat dissipation fins. The larger the surface area, the better the heat dissipation effect. The smaller the surface area, the worse the heat dissipation effect.
